A gas hot air gun includes a main body, an ignition device, a switch set and a safety switch. The main body includes a blower, a nozzle, a barrel and a handle. A heating chamber and a mixing chamber are on the inner front of the barrel. A gas can is inside the handle. One end of the nozzle is connected to the gas can. The switch set includes a power switch, with the safety switch closing power of the battery set or gas flow of the gas can under some pre-set conditions. Users press the power switch and have gas spray out from the nozzle into the heating chamber to generate heat. The blower sends hot air in the heating chamber out of the main body. A metal slice regulating the direction of air and a catalyst for avoiding flame extending out of the nozzle area are inside the heating chamber.
